Options for portable (laptop style) KVM?

Hello,

Does anybody happen to know of a portable KVM that is in a laptop style form factor? As in a clamshell design, where you flip up the monitor and it has a keyboard, just like a laptop, except it has no real functionality to it.

Instead, it allows you to plug in a server's monitor output/HDMI/USB (for keyboard/mouse), and since the device has it's own built-in battery, you're good to go.

Basically it would be like a laptop (monitor/keyboard) except it's just a dumb display w/keyboard and touchpad.

Any idea if these exist? If so, could you tell me of some? I've tried searching everywhere including Amazon but I couldn't find it and I think I'm searching for possible the wrong keywords.

Thanks!
